Childhood leukaemia in Belarus, Russia, and Ukraine following the Chernobyl power station accident: results from an international collaborative population-based case–control study

Abstract

Taken at face value, these findings suggest that prolonged exposure to very low radiation doses may increase leukaemia risk as much as or even more than acute exposure. However the large and statistically significant dose-response might be accounted for, at least in part, by an overestimate of risk in Ukraine. Therefore, we conclude this study provides no convincing evidence of an increased risk of childhood leukaemia as a result of exposure to Chernobyl radiation, since it is unclear whether the results are due to a true radiation-related excess, a sampling-derived bias in Ukraine, or some combination thereof. However, the lack of significant dose-responses in Belarus and Russia also cannot convincingly rule out the possibility of an increase in leukaemia risk at low dose levels.

Registration of childhood cancer: Moving towards pan-European coverage?

“…If concern arises in an area with no cancer registration, investigations must depend on ad hoc local surveys [86][87][88][89][90], which in any case cannot address the changes over time. For example, the effects of the Chernobyl accident on childhood cancer incidence could not be fully assessed in the most affected regions of Belarus or Ukraine, because cancer registration was not well established in the affected regions before the event [91]. In particular, national coverage would have allowed investigating a possible dose effect based on the geographical location of the relevant populations.…”

The Chernobyl and It’s Long Term Consequence: Clinical Cases of Leukemia

“…Studies conducted in the most contaminated regions found an association between radiation exposure and leukemia risk in Ukraine, Belarus, but not in Russia, and they are not statistically significant [15][16][17]. A study conducted in Greece reported an increase in infant leukemia among infants who were in utero at the time of Chernobyl accident but those findings were based on a small cohort of 12 patients exposed and 31 unexposed [18].…”
